Description
The AT49F4096A is a 5-volt, 4-megabit Flash memory organized as 524,288 words of
8 bits each or 256K words of 16 bits each. Manufactured with Atmel’s advanced non-
volatile CMOS technology, the device offers access times to 70 ns with power
dissipation of just 275 mW. When deselected, the CMOS standby current is less than
100 µA.
The device contains a user-enabled “boot block” protection feature. The AT49F4096A
locates the boot block at lowest order addresses (“bottom boot”).
To allow for simple in-system reprogrammability, the AT49F4096A does not require
high-input voltages for programming. Reading data out of the device is similar to read-
ing from an EPROM; it has standard CE
, OE and WE inputs to avoid bus contention.
Reprogramming the AT49F4096A is performed by first erasing a block of data and
then programming on a byte-by-byte or word-by-word basis.
